特性

Our Abpromise guarantee covers the use of ab640 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

  • 生理活性

    Determined by its inhibitory effect of the TNF-α mediated cytotoxicity in murine L-929 cells. The ED50 for this effect in the presence of 0.25 ng/ml of Recombinant Human TNF-α, is 0.125 μg/mL.

  • 機能
    Receptor with high affinity for TNFSF2/TNF-alpha and approximately 5-fold lower affinity for homotrimeric TNFSF1/lymphotoxin-alpha. The TRAF1/TRAF2 complex recruits the apoptotic suppressors BIRC2 and BIRC3 to TNFRSF1B/TNFR2. This receptor mediates most of the metabolic effects of TNF-alpha. Isoform 2 blocks TNF-alpha-induced apoptosis, which suggests that it regulates TNF-alpha function by antagonizing its biological activity.
  • 配列類似性
    Contains 4 TNFR-Cys repeats.
  • 翻訳後修飾
    Phosphorylated; mainly on serine residues and with a very low level on threonine residues.
    A soluble form (tumor necrosis factor binding protein 2) is produced from the membrane form by proteolytic processing.
  • 細胞内局在
    Secreted and Cell membrane.
  • Information by UniProt

Kindly clarify why is there difference in molecular weight (80 kDa and 19 kDa)
for human TNF receptor II full length proteins with catalogue numbers ab132049
and ab640, respectively.


Ab640 is a fragment of the TNF Receptor II protein. It is comprised of amino acids 33-205 but is an active protein. The activity was determined by its inhibitory effect of the TNF-α mediated cytotoxicity in murine L-929 cells. The ED50 for t...
